The most comprehensive trolling app on the market! Use it on the water to calculate your depth or use it at home to construct your own dive charts. This app lets you select your line, your lure, a diver or trolling weights, and then combine them however you want. Quickly and easily see the effect of changing line length, speed, weight, leader length, rod height, lures and many other factors. The app is continually improved and new lures and tackle are added regularly. This is a great app for anyone who fishes in saltwater, freshwater, or anywhere in between. The app has many features for walleye, trout, salmon, striped bass, red drum, tuna, wahoo, and pretty much any other species you might troll for. This app uses physics based calculations to determine the trolling depth of your lure with precision based on your inputs. The calculations have been verified via on the water testing.

Excellent support and very down to earth explanation on everything. Highly recommend. Terry

Excellent customer support

I had a question so I sent an email to the developer and within hours the question was answered. On my iPhone some of the lures were super imposed on top of other lure types he suggested I reduce the magnification of my text size and that fixed the problem. Then I had a few more questions and his responses were virtually immediate. This is a really excellent app for serious fishermen and it’s bound to only get better. Buddy K.

Great app for fishing!

We troll for Hybrids and Stripers most of the year. That may mean using Umbrella Rigs, Alabama Arigs, jigs with swim baits, snap weights, etc. This app lets you take into consideration the size of line, leader length, trolling speed, weight of lure, additional weight added, and even the height of the rod tip above the water. A typical setup we are using right now is trolling Alabama rigs with three, half ounce jigs, line and leader material are 50 pound Power Pro Depth Hunter line (no line counter reel required), three ounce Snap Weight. Here is the setup, trolling speed 2.5 mph, rod tip is five feet above the water. You let out the Arig with 25 feet of line (one color), attach 3 oz. Snap Weight. The App calculated 76.0 feet. You let out another three colors and put the rod in a holder. Your Arig will be running at 19 feet. The depth was verified with the Fish Hawk TD device. This summer, we were trolling at night with long baits like the Husky Jerk 10. We could see the fish on the Raymarine Axiom at 30 to 40 feet. Initially, we were using downriggers to get the baits down. Then we decided to use a Snap Weight approach with this app. The setup was always consistent, 25ft out - Snap Weight - 75ft out. We controlled the depth by the size of the snap weight, 2, 3, 4 oz, etc. Here was one of the calculations ... Husky Jerk 10, 4 oz. weight, 25/75, 1.8 mph, lure depth was 33 feet. We totally stopped using the downriggers for depths shallower than 40 feet. We could have never figured that out without this App!

Great App

Allows for many different selections. Ever since I’ve gotten it there has been a lot added as well, so the developer is always adding new things. Very impressed!

Great app

I use this app while fishing for walleye. After I put in the information of the gear that I am using and it puts my baits exactly where I want them.

Great value!

Great app, good lure selection and calculations look great
By Disappointed341

Great App for many trolling applications!

I use many of the trolling applications the App supports...I would like the app to accommodate leadcore as well then it would be a 5 star app. It is a good and simple tool to get you close. Just what I was looking for.

Great app for calculating lure depth

I’ve tried other apps but they “assume” too many variables. This app allows you to select line type, length, weights or divers and troll speed. With this entered information you will know exactly where your lure is running. Targeting your lure to the depth of the fish yields far more success than just guessing or worse using a different app with bad information.

Been waiting for this app

Simple to use, yet extremely accurate. Takes the guesswork out of trolling!
